About Us

Who We Are

Berkeley Lab’s Global Cooling Efficiency Program consists of scientists, engineers and policy analysts with a wide variety of skills, seeking to better understand cooling systems and to apply our knowledge and skills to meet cooling needs affordably and in harmony with the planet.

What We Do

Berkeley Lab’s Global Cooling Efficiency Program conducts technology and policy-relevant research on the energy efficiency of cooling equipment in order to:Nihar Shah explaining AC efficiency at a Montreal Protocol meeting

  • Maximize the energy, climate, monetary and public health benefits by improving energy efficiency in tandem with the refrigerant transition under the Montreal Protocol while minimizing the costs
  • Mitigate the negative impacts of the large expected growth in cooling demand due to various drivers such as increasing urbanization, electrification, income growth, and rising incidence and severity of heat waves
  • Expand access to cooling for underserved populations to increase community resilience


We support research institutions, businesses, governments and other organisations interested in establishing cooling efficiency and low-GWP refrigerant related research partnerships.
